Japan's 18-year-old Prince Hisahito says he'll balance royal duties and university studies

TOKYO (AP) — Japan's Prince Hisahito, the second in line to the throne, held a debut news conference Monday, telling reporters he would try to balance official duties and his university studies and research about the dragonfly.

Hisahito turned 18 last September, becoming the first male royal family member to reach adulthood in almost four decades in Japan. It was a significant development for a family that has ruled for more than a millennium but faces the same existential problems as the rest of the nation — a fast-aging, shrinking population.

The prince said he would follow the good examples of his uncle, Emperor Naruhito, and other elder members of the imperial family, while pursuing his university studies, beginning next month.

Speaking to reporters at the Akasaka Estate residence in Tokyo, Hisahito said he believes the role of the emperor as a symbolic figure is someone who “always thinks of the people and stays close to them.”

Hisahito is second in line to Japan's Chrysanthemum Throne after his father, Crown Prince Akishino.

The prince, who turned 18 on Sept. 6, is the youngest of the 16-member imperial family and one of only five men, including former Emperor Akihito.

The 1947 Imperial House Law only allows a male to succeed to the throne. Female royal members who marry commoners lose their royal status.

Hisahito's older cousin, Princess Aiko — the only child of Naruhito and his wife Masako — is seen as the public’s favorite, though the law for now bars her from becoming an empress, despite being in a direct line of descent.

Japan's conservative government wants to keep the royal succession male-only, though it is looking for a way to allow women to keep royal status if they marry commoners.

Hisahito plans to study biology at the Tsukuba University near Tokyo, starting in April. He hopes to focus his studies on dragonflies.

Apart from researching dragonflies and other insects, Hisahito told reporters he is also interested in studying ways to protect insect populations in urban areas. His other interests lie in growing tomatoes and rice on the palace compound.

Because Japanese royals have to stay away from politics, members of the Imperial Family tend to study biology, literature and arts. Naruhito's specialty is water transport while his father, Emperor Emeritus Akihito who abdicated in 2019, researches fish. Hisahito's father, Crown Prince Akishino, is an expert of chickens.

Japan will hold a coming-of-age palace ceremony for Hisahito on Sept. 6, his 19th birthday.

YEREVAN, Armenia (AP) — European leaders on Monday said that U.S. President Donald Trump’s snap decision to pull thousands of U.S. troops out of Germany came as a surprise but is a fresh sign that Europe must take care of its own security.

The Pentagon announced last week that it would pull some 5,000 troops out of Germany, but Trump told reporters on Saturday that “we’re going to cut way down. And we’re cutting a lot further than 5,000.”

He offered no reason for the move, which blindsided NATO, but his decision came amid an escalating dispute with German Chancellor Friedrich Merz over the U.S-Israeli war on Iran, and Trump’s anger that European allies have been reluctant to get involved in the conflict in the Middle East.

Asked about the decision to pull out 5,000 troops from Germany, Norwegian Prime Minister Jonas Gahr Støre said: “I wouldn’t exaggerate that because I think we are expecting that Europe is taking more charge of its own security.

“I do not see those figures as dramatic, but I think they should be handled in a harmonious way inside the framework of NATO,” he told reporters in Yerevan, Armenia, where European leaders are holding a summit.

The European Union’s foreign policy chief, Kaja Kallas, said “there has been a talk about withdrawal of U.S. troops for a long time from Europe. But of course, the timing of this announcement comes as a surprise.”

“I think it shows that we have to really strengthen the European pillar in NATO,” she said.

Asked whether she believes that Trump is trying to punish Merz, who said that the U.S. has been humiliated by Iran in talks to end the war, Kallas said: “I don’t see into the head of President Trump, so he has to explain it himself.”

Over the weekend, NATO spokesperson Allison Hart said that officials at the 32-nation military alliance “are working with the U.S. to understand the details of their decision on force posture in Germany.”

European allies and Canada have known since just after he came to office again last year that Trump would pull troops out of Europe — indeed some left Romania in October — but U.S. officials had pledged to coordinate any moves with their NATO allies to avoid creating a security vacuum.

NATO Secretary-General Mark Rutte played down the move, saying that “there has been at this point disappointment on the U.S. side” about European support for the war on Iran.

Notably France, Spain and the U.K. have declined to give U.S. forces free rein to use bases on their territory to attack Iran. Spain has denied them the use of its airspace and bases there for the war.

But Rutte, who has championed Trump’s leadership at NATO despite the U.S. president's criticism of the majority of the allies, said: “I would say the Europeans have heard a message. They are now making sure that all the bilateral basing agreements are being implemented.”

Rutte added that European nations “have decided to pre-position assets, key assets, close to the theater for the next phase.”

He provided no details, but the Europeans have insisted they would not help police the Strait of Hormuz, a key energy trade route, until the war is over.

French President Emmanuel Macron said “if the United States is ready to reopen Hormuz, that’s great. That’s what we’ve been asking for since the beginning.” But he underlined that the Europeans are not ready to get involved in any operation “that does not seem clear to us.”

In another sign of friction with Merz, Trump has accused the EU of not complying with its U.S. trade deal and announced plans to increase tariffs next week on cars and trucks produced in the bloc to 25%, a move that would be particularly damaging to Germany, a major automobile manufacturer.

Without mentioning Trump or the United States, European Commission President Ursula von der Leyen listed recent trade deals that the bloc has sealed with Australia and India, and is now working on with Mexico.

“With like-minded friends, you have stable, reliable supply chains and Europe has the biggest network of free trade agreements,” von der Leyen, who is from Germany, told reporters.
